Abstract

With distributed generation being introduced in the meshed distribution networks under increased loading conditions, maintaining the system voltage stability will become one of the major concerns. The conventional approach of repetitive power flow solutions fails to obtain the critical loading point as Jacobian becomes singular before maximum loading point. Continuation power flow methods, based on the predictor-corrector scheme, overcome this difficulty with the use of parameterization techniques. Continuation power flow tools, already developed for transmission systems, need to be extended to handle three phase unbalanced distribution systems. This research work contributes towards development of a robust and efficient three phase unbalanced continuation power flow tool for voltage stability assessment of shipboard power systems and terrestrial distribution systems. The developed continuation power flow method is based on adaptive step length control and pseudo arc length/local parameterization technique, which have been tested on several I test systems and a shipboard power system.
